FORT MYERS, Fla. — A day later, there still was no timetable for Jacoby Ellsbury.

Ellsbury suffered a right oblique strain during batting practice Friday morning, and on Saturday, Aaron Boone didn’t have much more to offer regarding Ellsbury’s prognosis than he had when it occurred.

“Similar today,” Boone said before the Yankees’ 5-3 victory over the Red Sox at JetBlue Park that raised their exhibition record to 8-1. “It’s [the discomfort] still in there. Not a lot of work for him. It’s something we’ll continue to monitor. There’s still that tweak in there.”

Ellsbury came into camp hoping to win back the job of starting centerfielder he lost to Aaron Hicks last season. The latter, coincidentally, was limited to 88 games in 2017 after suffering oblique strains on each side.

“It’s not a fun process,” said Hicks, who hit his first homer of spring training Saturday, driving a 96-mph fastball from righthander Joe Kelly to right-center. “Because it’s literally just sitting around waiting until there’s no pain. It’s just a waiting game.”

That’s the reason Boone wasn’t any closer to a time frame.

“Even though we believe it’s a mild strain, oblique’s a tricky thing,” he said. “Like a hamstring or groin, you need to be healthy because as soon as you’re not and you go out and push it, you set yourself back even more. We’ll be conservative with how we treat it. Hopefully it won’t be too long.”

Slow go for Frazier, too

Boone said Clint Frazier’s MRI “was clean,” though the outfielder isn’t any closer to resuming activity. He suffered a concussion the previous Saturday.

“He came in and I think we sent him home,” Boone said. “But all in all, he came in and said he felt a little better. Hopefully it’s not something severe.”

Frazier is scheduled to be evaluated by the team doctor Sunday morning.

Gleyber’s struggles

Infield prospect Gleyber Torres, competing for the job at second base, has gotten off to a slow start, though he ripped a double off the wall in left in his third at-bat Saturday to finish 1-for-3. In the field, it’s been a mixed bag. Torres turned a nice 4-6-3 double play in the second inning on Brock Holt’s grounder but misplayed Holt’s one-hop smash in the fourth. The ball skittered away and Torres threw wide of the plate while trying to cut down Xander Bogaerts.

“I felt good about the double,” said Torres, who is 2-for-16. “The [first week] was a struggle. I’m working right now on my timing.”

Sharp Sevy

Boone did not ride the team bus here and instead drove down after staying in Tampa to watch several of his pitchers, including Luis Severino, throw simulated games. “Real sharp,” Boone said. One observer said Severino, slated to make his first start Thursday, recorded 11 outs in his three innings, seven on strikeouts.

Wilson has a ball

Seahawks quarterback Russell Wilson, in camp all week, had his final workout with the club Saturday morning. Wilson, who is scheduled to depart Tampa on Sunday morning, gave each of his teammates an autographed football.
